zclsyntax: visit both LHS and RHS of binary op in walk
...
Due to a typo, it was previously visiting LHS twice, and destroying the
RHS by overwriting it by LHS.

zclsyntax: operations are now pointers to a struct value
...
Previously operations were an enum, but we've ended up needing to store
a collection of values against each, so an operation being a pointer to
a struct feels more natural.
This in turn allows us to more easily fix the return types of the
operations, so that we don't need to do any unusual work to understand
that (for example) arithmetic always returns a number.

Not actually tested yet, since it can't be used until parseExpressionTerm
works.
